Statistics Problem Set

2. This histogram is unimodal, is basic entirelyy symmetric, but is some skew amend. The center of the histogram is mingled with 90 and 110, but more precisely, is 102. The IQR is 46 range points, the cadence division is 29.6, and the over any range of the range points is 111. The Data shelve says that blow represents bonnie result for all cars, yet, for Mid-Size Cars, there is a big flesh of cars with a evaluation high(prenominal)(prenominal) than 100, than the number of cars with a rating lower than 100. This suggests that Mid-Size Cars ar less(prenominal) preventative than the otherwise types of cars that were reviewed ( humble Cars and vast Cars). This Mid-Size Car data would ensnargon shifted the average up, therefore, one or twain of the other types of cars moldiness have fewer go Insurance Injury losses in 2000-2001. beautiful CarsMid-Size Cars extensive Cars upper limit24716992 Q314712577 Median133.510268 Q11047957.5 Minimum635839 Mean134.5104.668.1 normal Deviation50.329.614.2 4. See connect 5. twain the Small and Mid-Size cars would produce a relatively unimodal histogram graph. both types of cars would make histogram graphs that would be skew correct, the Small Cars histogram graph creation more skewed to the right than that of the Mid-Size Cars. While the minimum of both the Small Cars Ratings and the Mid-Size Cars are genuinely close, their maximums differ greatly, the Small Cars Maximum rating being much higher. This fact alone causes the Small Cars mean, standard deviation, and maximum (evidently) to be much higher than that of the Mid-Size Cars. Further, the Small Cars Ratings center is a higher number than the Mid-Sized Cars, shifting all of the values not mentioned higher up (Q1, Q2, IQR) up, or to a higher value. 6. See attached 7. in that respect are no outliers within the ratings of the Large Cars because none of the ratings are extreme in comparison to the other Large Cars ratings. Yes, there is a paste between the ratings of one hundred ninety and 221, but this gap is not...If you fate to get a wide essay, order it on our website: Ordercustompaper.com
